No, you are correct. This is not the only example that I would suggest questions their mandate and democratic processes. But there a quite a few topics that add up.
This law is a very plain case of trying to enact a law serving special interests. Just look at how it came to be and who is responsible for that. It is a form of nepotism that does indeed question legislative processes.
The mandate of any democratic government is only valid as long as enough people believe in it. And stunts like these create doubt.
You should remember that for the next time you point the finger towards euro-critical movements.
Shit like this isn't necessary, doesn't solve any problem and is certainly not in the general interest of the population. Because it just servers special interests.
edit: And just to add: enacting laws via the EU to evade domestic criticism is a widely known and often employed political tactic. There are countless examples of this.
